Jacks SRT 6.4lt making the mumbo!!

Cam, pistons and rods deal. Whipple 3.0. Super drivable and ready to Roll race.

Some road data next week and it should be headed home after testing the trans on the road for driveability.

This one is making the juice !!! 16psi, pump 98. If you doubt me, come past monday and ill show you before its taken off the dyno.

We work with the best on Hemis in the country and that means we deliver the results !

Jack wanted 900-950.... let's just say, i think RJM and Jack are delivering the goods to WA hemi owners. 970hp motor and blower only and a little extra in the pipeline for the heavy hitters !

💙 TODAY’S THE DAY! 💙

From 1 October 2026, businesses can no longer pass card payment surcharges on to customers.

At RJM Custom Automotive, we’ve decided to take a slightly different approach.

Rather than adding those extra payment costs into our pricing, we’d love to encourage our customers to use Bank Transfer, PayID or good old CASH wherever possible.

💙 SO WE’RE OFFERING A 2% DISCOUNT! 💙

Customers who choose to pay their invoice by Cash, PayID or Bank Transfer will receive 2% off their invoice total.

It’s our way of saying THANK YOU for choosing a payment method that helps us keep our processing costs down.

Card payment? No problem!
You can still pay by card — there’s no surcharge.

We simply want to give our customers another option and reward those who choose an alternative payment method.

Thanks for your continued support of RJM Custom Automotive! 🖤💙

Ok, so here is how we dial in our shift points now in an attempt to maintain our drivers licence! Haha

This is Chris's Trackhawk. (This will be news for Chris) making a F**ken Whopping 890hp on pump 98 fuel at 6400rpm , and only 16psi boost, we just simply can NOT test wide open shift points on the street with a car like this. For reference, the 7->8 shift you hear on this one... its at 310km/h.... let that set in!!!!! Shifting into top gear at 310km/h and enough power to push well into the 350km/h mark! Killah stereo, moon roof, heated seats and pump fuel from any reputable 98 supplier... is there really a better combo out there ?

This is one of our stage 2 NSR camshafts for the trackhawk and man does this one delivered the goods!

INOVIT Rotor, looking all sorts of perfect on the FG Falcon XR6 Turbo.
We Slammed Jas's FG on some XYZ Coilovers, supplied and installed the Rotor wheels as we are the agent for Inovit in Perth.

I cant express how great this combo looks in real life. Just perfect for the street!

Thanks for choosing us again mate!
